Server stops with no error or reason

I have installed bukkit correctly to my linux vps and it does start and run, you can even connect and play but after anywhere from a minute to 10 minutes the server just stops. No error no crash it just stops and exits to the terminal. The bukkit version is unimportant as I've tried several versions and even vanilla minecraft resulting in the same problem. Java is also working correctly but i even reinstalled it just to be sure. I honestly have no clue as to whats going on.

Code:

srv400@server:~$ nice -n 0 java -Xincgc -Xmx1024M -jar craftbukkit-0.0.1-SNAPSHOT.jar -c server.properties -h 173.0.60.203 -p 25565 -o true -s 12 -w world

I appear to be the first person with this problem as of yet.

Bump. I have a paying client waiting for this to be resolved.

 

Hmm I have actually had this problem before, my JVM crashed thus causing the server to crash. But my problem was caused by an anti-cheat program from another game I was running that didnt like console windows
btw create a .sh file with nano with your param's and try running that

 

The server already runs with a start up script inside a screen.

 

Bump with help getting a little annoying now we have an update too it literally crashes every 5 minutes from the point of the last crash. Any Help would be apperciated.
